Answer:
Sinx = 5/13
cosy = 5/13
cosy = sinx ; they both share a proportional relationship
Step-by-step explanation:
From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;
sinx° = opposite / hypotenuse
From Pythagoras ;
Hypotenuse = √(opposite² + adjacent²)
Hypotenus = √(12² + 5²)
Hypotenus = 13
Sin x° = opposite / hypotenus = 5 / 13
Sin x° = 5/13
Cos y = adjacent / hypotenus = 5 / 13
Hence,
sinx = cosy
Therefore, they both share a proportional relationship.
Answer:
x² - 4x + 3 = 0
Step-by-step explanation:
given roots x = a and x = b then the corresponding factors are
(x - a) and (x - b)
the equation is then the product of these factors , that is
(x - a)(x - b) = 0
given
roots x = 3 and x = 1 , then factors are (x - 3) and (x - 1) , then
(x - 3)(x - 1) = 0 ← expand factors using FOIL
x² - 4x + 3 = 0
